= Load tank time out
This type of signal appears some minutes after loading starts if the machine does not take on any
water.
When this signal is displayed, check that the overflow plug is inserted, check the water supply
circuit upstream of the machine (e.g. squashing of the pipe, broken valve, no water in the pipe…).
If this signal is shown, call in a trained technician.
= Tank probe open
If this signal occurs call in a trained technician.
= Tank probe short circuit
If this signal occurs call in a trained technician.
= Boiler probe open
If this signal occurs call in a trained technician.
= Boiler probe short circuit
If this signal occurs call in a trained technician.
= Boiler temperature excessive
If this signal occurs call in a trained technician.
= Tank temperature excessive
If this signal occurs call in a trained technician.
= Electro-mechanical safety
This signal appears when the electronic card does not intervene when a state of “boiler temperature
excessive”, or “tank temperature excessive”, or when the safety pressure gauge breaks down.
The tripping of this safety device automatically switches the machine to the drain cycle. In most
cases involving the safety pressure gauge, draining the machine solves the problem without causing
the signal to reappear. When this is not the case, the signal appears and the machine cuts out.
If this signal is shown, call in a trained technician.
